Yankuang Energy Group Company Limited has formalised the “Detailed Working Rules for the Sustainable Development Committee of the Board of Directors,” introducing a dedicated governance body to oversee the company’s environmental, social and governance (ESG) strategy and risk management.

The newly formed Sustainable Development Committee is mandated to: • Evaluate risks and opportunities related to corporate governance and ESG matters, providing recommendations to the Board. • Review and refine company policies, internal controls and management systems to ensure compliance with regulations issued by the China Securities Regulatory Commission (CSRC), the Hong Kong Stock Exchange (HKEX) and other relevant authorities. • Monitor implementation of ESG objectives, assess progress and supervise the preparation of the company’s Social Responsibility Report. • Guide long-term vision, objectives and strategies for sustainable development and submit findings and resolutions to the Board.

Committee Structure • The committee comprises three directors, including one chairperson elected by the Board. • Members are nominated by either the Board Chair, more than half of independent directors, or one-third of all directors, with tenure aligned to their Board terms and eligibility for re-election. • The company’s Operations Management Department will act as the working body, coordinating information and daily tasks.

Governance Processes • Meetings are required at least once annually; notices must be issued three days in advance. • A quorum of two-thirds of members is mandatory, and resolutions pass with a simple majority. Meetings can be held in person, via video or teleconference, and may invite other directors or senior management. • The committee can engage external advisers at the company’s expense to obtain independent professional opinions. • Detailed minutes must be recorded, signed by attendees and submitted to the Board; all participants are bound by confidentiality obligations.

Implementation The Working Rules take effect upon Board approval and will guide Yankuang Energy’s pursuit of enhanced sustainability governance, ensuring alignment with evolving regulatory standards and stakeholder expectations.
